SPECIFICATION forming part of Letters Patent No. 627,325, dated June 20, 1899. Application filed O ctoher19, 1898. Serial No. 693,956. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM P. CORSON, a citizen of the United States, residing at Salem, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Shade-Roller Brackets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to curtain or shade roller fixtures for supporting the rollers of window-shades, and has for its object to produce a shade-roller holder or fixture which shall be simple in construction, eflicient in action, readily applied to the windowframe, and cheap to manufacture.

To the above end the present invention consists of the shade-roller fixture which will be hereinafter described and claimed.

Thepresent invention is shown in the accompanying drawings, in which- Figure 1 shows in side elevation the member which supports the end of the shaderoller having the cylindrical stud or post. Fig. 2 shows in side elevation the member which supports the end of the shade-roller having the flattened post. Fig. 3 is a front elevation of the member shown in Fig. 1. Fig. 4 is a front elevation of the member shown in Fig. 2. Figs. 5 to 8 illustrate a set of fixtures in which the member which supports the end of the roller having the fiattened post is slightly modified.

Similar letters of reference will be employed to designate corresponding parts throughout the specification and drawings.

Prior to the present invention it has been proposed to provide shade-roller fixtures or supports comprising two members arranged to be screwed directly into the window-frame and having heads provided with suitable bearings to receive and support the posts at opposite ends of the shaft-roller; but in such prior construction, owing to the fact that the bases of the heads of the fixtures were formed tapering or flaring, it was necessary in putting the fixtures up to make two borings in forming the holes to receive them, one for the threaded shank and one for the flaring head, or, more accurately speaking, form counterends flush with the window frame it was neces= sary to fit the shade-roller with great nicety of adjustment as to its length in order to insure the engagement of its posts with the seats of the fixtures. Furthermore, in the device of the prior art there was no provision for keeping the flattened stud of the shaderoller in its fixture, and consequently it was constantly flying out, and thus allowing the shade-roller to drop out.

The difficulties of the prior device have been overcome by the present invention, wherein A and A represent the opposite members of a pair of shade-roller fixtures. The member A has a cylindrical head a and the member A has a cylindrical head a, and each member has a cylindrical screw-threaded shank a the threads of which project beyond the periphery of the respective heads a and a. The member A has a cylindrical bearing a to receive the cylindrical post of the shade-roller andis provided with notches a to receive the end of a screw-driver when inserting the memberAin the window-frame. The head a of the member A is provided with the usual open slot or hearing a to receive the flattened post of the shade-roller. In use the brackets or fixtures A and A. are secured in the window-frame by first forming a cylindrical bore or hole therein and screwing the members A and A into holes at opposite sides of the window-frame, leaving the heads a and a, projecting more or less, the distance being determined by the length of the shade-roller, as the members A and A in the present device can be adjusted to support shade-rollers of varying length within a given limit.

In order to maintain the flattened post of the shade-roller in the slot a of the member A, there is provided a suitable detent to close the upper open end of the slot of, said detent in the form of the invention shown in Figs. 2 and at Comprising a rubber band a, surrounding the head a and spanning the open end of the slot or", thus effectually closing the slot a and preventing the flattened stud of the shade-roller from jumping out.

In the modification of the device shown in Figs. 5 to 9, inclusive, the member A is substantially the same as the member A just described; but the member A which corresponds to the member A, has been modified in so far as the detent which closes the slot a is concerned. In the member A the detent consists of a metallic ring M, which is arranged to be supported on and turn on the head a by means of a pin a fixed in said head and engaging a slot at in the base of the ring (1 The ring a on one side is provided with a slot at which extends through its outer end, which when the ring at is turned to bring the slot a over the open end of the slot (L as shown in Fig. 8, will permit the flattened post of the shade-roller to be inserted in the slot at and when turned to the position shown in Fig. 9 will close the said slot a and prevent the flattened post of the shade-roller from accidentally jumping out of its hearing a The operation of the device has been sufficiently described in connection with the foregoing description of its form and arrangement, and further description thereof is deemed unnecessary.

It will be noted that in the present construction, inasmuch as the cylindrical heads are somewhat smaller in diameter than the threaded shanks, the range of adjustment of the brackets toward and from each other or toward and from the endsof the shade-roller is quite extensive, for, notwithstanding the presence of the detent-rings a and a the members A and A may be turned into the recesses of the window-frame until the heads are received therein, if desired, without disturbing the said detent-rings.

Having described the construction and mode of operation, I claim as new and desire to protect by Letters Patent of the United Statesp 1. A shade-roller bracket or support comprising two members each of which has a sub stantially cylindrical head and a threaded shank of larger diameter than the head, the head of one member provided with a bore and the head of the other member with an open slot or seat, and a detent-ring on the head of the slotted member arranged to close the slot therein, substantially as described.

2. A shade-roller bracket or supportcomprising two members each of which has a substantially cylindrical head and a threaded shank, the head of one member provided with a bore and the head of the other member provided with an open slot, and an elastic ring supported'on the head of the slotted member and arranged to close the slot therein, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM P. CORSON.
